[Dovecot] Active Directory authentication

[Dimitrios Karapiperis]

Hello all

I would like to ask if there is adequate mechanism to authenticate users
through POP3 against Active Directory by Outlook Express so that users will
authenticate seamlessly using logon credentials.

I have implemented  LDAP authentication but users must supply their
credentials to Outlook Express although they have logged on to Windows (AD).

the ntlm auth in Dovecot 1.1 (windind) satisies this requirement (no
credentials in Outlook)?

thanks
Dimitrios
